The main purpose of this study was to examine the effect of teachers' and students' thinking styles on students' satisfaction with the course followed and on their learning process. The sample was made up of 102 instructional psychology college students who responded to two administrations of the Thinking Style Inventory, one about their teacher and one about themselves, to a satisfaction scale referring to the instructional process, and finally to a scale designed to measure the time and effort they devoted to the learning process. Multivariate regression analyses were carried out. Results reveal that both teachers' and students' thinking styles are good predictors of students' satisfaction and their involvement in the learning process. (Contains 5 tables.)
